Iron falling through floor in sunken crypts

[Yourbestbuddy1]

Anyone else finding a few pieces of raw ore laying around a crypt after clearing it out? It's happened on every crypt I've cleared so far. I'm guessing some is falling through the floor while mining scrap piles in the crypt. I'm playing vanilla with standard settings except for no events.

To clarify, I meant that the ore is laying outside of the crypt in the swamp. I have to run around the crypt, sometimes a fair way out, to find it all.

iirc some of the muddy scrap pile pieces that you mine through are technically outside the dungeon's geometry, which itself is (correct me on this if I'm wrong) high in the skybox far above the game world. I think what might be happening is that if you destroy a piece through mining that is just far enough outside the dungeon geometry, it falls down to the world map below, which is why you find bits of iron, leather scrap, and sometimes withered bones laying around the swamp nearby.

Yep, this exactly. Even if it is inside the crypt geometry it can bounce when it hits the ground.

You can see the same thing happen when you mine copper. After the node breaks there is a few mili-seconds delay while the stone and ore drop from the sky and bounce around.

I had couple of cases of that and then found those ore outside the crypt on the ground when I got out

Yes that is correct, it can be also recognized if you mine the Stones
(similar looking to the Copper Veins) in the Blackforest.

As soon as you hit a piece which is slightly underground, a whole bunch of
Stones is popping out of the ground a few seconds after you hit that certain
piece of Stone.

If you crank up the Resource modifier to 3x you will see this more clearly.

How would this be related to mining out-of-geometry mud piles in dungeons?!

Chill. They're describing another situation where you can clearly and more obviously observe the item drop behavior in the open world to better understand how that behavior can cause iron scrap to wind up outside the dungeon geometry. It's not as obvious inside the cramped confines of sunken crypts.

Its the exact same mechanic in each case just easier to see with copper/stone. The dungeon/crypt layer is not below ground its the highest layer. The bottom of the crypt layer touches the top of the sky layer. The terrain modification floor also touches the top of the sky layer.

Valheim is a proc gen game and like all other proc gen games clipping is an issue. You may have noticed tames with their heads protruding through structures or a skeleton archer or graydwarf rock thrower stuck inside a boulder that they can still shoot out of.

Ore, scrap, and stone that clips through the bottom of the dungeon layer or terrain modification floor pushes into the sky layer and drops through all the other elevation levels to the ground. Clipping is all most impossible to solve in a proc gen game. So always walk around the ground level layer after mining to find/pick up the ore/scrap/stone, that clipped through the bottom of the crypt layer/terrain modification floor.

I understand for instances and mobs got clipped in obstacles, but that part about terrain modification layer being "high in the sky" is hard to swallow. With this in mind, I'll pay more attention when mining. That would mean that sometimes when you dig a pit, you'll find some pickable rocks not at the bottom floor, as gravity would expect it, but at ground level on the edge of the pit, correct?

They at some point changed how it works when spawning the resources. Properly due to some issues with the xBox behavior. At least it was after the xBox release I noticed this.
What is likely happening, is that it now try to determine the "ground", but something in the crypt is blocking, so it get pushed upwards until it is outside.

In programming terms its an overflow (or underflow) error. If each layer is one number higher and the layers are 1-100 if you start adding one when you hit what should be 101 it rolls back to 1. Going the other direction if you start at 100 and subtract 1 when you hit what should be 0 it flips to 100. Rounding errors can cause a problem with a set up like this. Failing in your programming to write checks for over or underflow can cause this and proc gen that works along the edges cause this.

The devs changed how it works when Ashlands came out but they never explained why they made that change.
